With Cosmos DB, Microsoft wants to build one database to rule them all | TechCrunch


Cosmos DB is the new globally distributed database Microsoft is launching at its Build developer conference today. The project that started seven years ago to prototype what a globally distributed (or “planet-scale,” as Microsoft often likes to call it) database would look like. This project was called “Project Florence”, turned into DocumentDB, Azure’s NoSQL database service, and is now morphing into Cosmos DB.

    Microsoft introduces Azure Cosmos DB, a globally distributed database with 5 consistency choices

    Arguably the biggest Azure news to come out of Microsoft’s Build 2017 developer conference is the debut of Azure Cosmos DB. The schema-free database service offers developers flexibility with five consistency choices, instead of forcing them to choose between strong and eventual consistency. The five models are as follows: Strong, Bounded Staleness, Session, Consistent Prefix, and Eventual.

    Cosmos DB is a superset of DocumentDB, the company’s cloud-based NoSQL database for storing and serving up information for applications in JSON. Scott Guthrie, executive vice president of the Microsoft Cloud and Enterprise group, described it as “the first globally distributed, multi-model database service delivering turnkey global horizontal scale out with guaranteed uptime and millisecond latency at the 99th percentile.”

    He promised service-level agreements across four dimensions: high availability, performance latency, performance throughput, and data consistency. Other highlights include high performance, fault tolerance, being able to elastically scale across any number of geographical regions, and automatically indexing data.

    Guthrie said onstage that 90 percent of Fortune 500 companies are using the Microsoft Cloud. That number is up from 85 percent at Build 2016.

    Azure IoT Edge arrived in preview. The technology, which supports both Windows and Linux, extends cloud computing to IoT devices.

    Open source database firm Cockroach Labs raises $27M Series B led by Redpoint, and announces an enterprise version

    Cockroach Labs announces $27M Series B and enterprise tier for its reliable database

    “A database that replicates itself and is meant to survive” — that was the connection that Cockroach Labs CEO Spencer Kimball made between the startup’s memorable name and its value proposition. Despite entering a crowded market, Cockroach has been able to gain the favor of some of the best known VCs in tech. Today’s $27 million Series B is being led by Redpoint with participation from Benchmark, GV, Index Ventures and FirstMark.

    At its core, CockroachDB is an open-source database service optimized to reduce downtime. Every time you visit a website, every time you check your bank account and every time you log into your favorite social networking app, you’re dependent on databases to be ready and able to feed you necessary information.

    CockroachDB quite literally replicates itself like an insect and distributes information so it doesn’t become a sitting duck, or die if we’re keeping with the metaphor. The company calls this feature multi-active availability.

    Originally started as a GitHub project, Cockroach will be monetizing around a paid enterprise tier. This premium version will include distributed backup and restore functionality in addition to enterprise support— things that are not optional for serious users managing large amounts of data.

    Chinese tech conglomerate Baidu is one of Cockroach’s earliest customers. The company has been testing Cockroach, processing two billion inserts a day while simulating nightmare scenarios to check for resiliency.

    Cockroach differentiates itself from Google CloudSpanner by being open source, but geo-partitioning can only help the company further differentiate.
